Identification of a Baeyer–Villiger monooxygenase sequence motif
l‐Galactono‐γ‐lactone dehydrogenase from Arabidopsis thaliana, a flavoprotein involved in vitamin C biosynthesis
The present study provides the first biochemical characterization of AtGALDH and some active site variants and the Leu56 variants showed remarkable differences in Michaelis constants for both l‐galactono‐1,4‐lactone and l‐gulono‐ 1, 4‐lactsone and released their FAD’cofactor more easily than wild‐type AtGalDH.

The screening of 50 sorghum varieties showed that, on average, germination did not affect the content in total phenolic compounds but decreased the content of proanthocyanidins, 3-deoxyanthocyanids, and flavan-4-ols, which are useful indicators for the selection of sorghums for food and agronomic properties.

A novel phenol hydroxylase (PheA) that catalyzes the first step in the degradation of phenol in Bacillus thermoglucosidasius A7 is described and is the first member of a newly recognized family of short-chain flavin reductases that use FAD both as a substrate and as a prosthetic group.

MS analysis showed that six peptides, including the N‐terminal sequence of SPC4 matched with the predicted tryptic peptides of gene indice TC102191 of sorghum chromosome 1, indicating thatTC102191 codes for the N-terminal part of the sequence ofSPC4, including a signal peptide of 31 amino acids.
Elucidation of the 4-Hydroxyacetophenone Catabolic Pathway in Pseudomonas fluorescens ACB
Evidence is provided that hydroquinone is further degraded through 4-hydroxymuconic semialdehyde and maleylacetate to beta-ketoadipate and it is proposed that the hapC and hapD gene products are involved in the ring cleavage of Hydroquinone.
Hydroquinone Dioxygenase from Pseudomonas fluorescens ACB: a Novel Member of the Family of Nonheme-Iron(II)-Dependent Dioxygenases
N-terminal sequencing and peptide mapping and sequencing based on matrix-assisted laser desorption ionization--two-stage time of flight analysis established that the HQDO subunits are encoded by neighboring open reading frames (hapC and hapD) of a gene cluster, implicated to be involved in 4-hydroxyacetophenone degradation.
